Powder Metallurgy Research Institute, Central South University, Changsha 410083, China;2. School of Metalllurgy and Environment, Central South University, Changsha 410083, China)Abstract:A process of purification of coal-based coke powder as anode for Li-ion......
Studies on Preparation of Onion-like Fullerenes by Vacuum Heat-treatment Wang Xiao-min1,LIU Xu-guang1,XU Bing-she1,Zhang Yan1,HOU Li-feng1 (1.College of Materials Science and Engineering, Taiyuan University of Technology, Taiyuan, Shanxi, China) 摘要:Onion-like Fullerenes were produced at high-temperature in vacuum. The morphology of the carbon nano onion-like fullerenes was examined......
Flexible Furnace Concepts for Vacuum Heat Treatment Combined with High-pressure Gas Quenching Karl Ritter1,Stefan Wiebach1 (1.ALD Vacuum Technologies AG, Hanau - Germany) 摘要:IN the past five years the process combination of vacuum hardening, respectively vacuum carburizing with high-pressure gas quenching was successfully introduced to the market, especially in the manufacture of gears......
-component alloy to recover valuable metal Cu by sulfuration-vacuum distillation was theoretically analyzed. The effects of addition of sulphur, distillation temperature and distillation time... rates are increased respectively to 99.96%, 95.17%, 99.94%, 99.84%. Impurity removal effect of sulfuration-vacuum distillation is significantly better than that of direct vacuum distillation......
